PETSc configure cannot build it with the option --download-mpich=1 [or the alternate mpi with --download-lam=1]. If you know how to build it yourself, and then configure PETSc with it - then that should work. No one has attempted this on windows yet [as far as I know]. Why would you prefer to build MPICH from sources on windows - when the binary install is available? Satish
